Hi Paul,
Sascha here from Northern Light Modular...
We are very much looking forward to integrate the new IC into our upcoming Polymorpher - 2OCx for the Buchla format.
Right now I am looking into implement all the input and output attenuation...
Quick followup, O_C T4.1 is now in beta testing. Here's a photo of one of the beta test units being calibrated.
Full open source release is likely soon, of course depending on feedback from beta testers in the coming days. But so far...
